Specification of Letters Patent.

Patented A110'. 27, 1919.

Application led August 31, 1910. Serial No. 579,810.

To all 'whom t may concern Be itknown that-I, CHARLES Kniennnv, a citizen of the United States, and a resident of' Vineland, Cumberland county, New J ersey, have invented certain Improvements in Lasting-h/Iaehines, of which the following is a specication.

One object of my invention is to provide a machine particularly designed to facili tate the lasting of shoes; it being desired that the various parts shall be so arranged as to permit of the machine being operated with the utmost rapidity as well as in a satisfactory and efficient manner.

I further desire to provide a lasting machine which shallbe capable of adjustment for operation with either right or leftlasts of practically any size or shape; it being .especially desired that the arrangement ot parts shall be such as to so apply the leather to a last as to produce the highest grade ot' shoes.

I also'de'sirti: that the machine constructed according to my invention shall, atter prop- Aso erly applying and'st-retching t-he leather on the last, also be capable of placing'in position a leather-retaining cap for use'instead of the tacks or wires customarily used to hold the leather to the front portions ot a shoe, and in addition be adjustable to give free access to the heel ofthe last.l

i Another object of my invention is to provide a last-ing machine, which in addition to stretching an upper over certain portions of a last, shall be capable of manipulation to smooth or wipe such upper so that it takes the desired shape.

Another object of the invention is to provide a machine capable of lasting shoes practically without tacks, strings. wires or other Vtemporary fastenings, so that the shoes n1a}v be advertised and sold as tacklcss lasted.

These Aobjects and vother advantageous ends I secure as hereinafter set forth. reference being had to the accompanyin;r drawings, in which Figure 1, is a vertical section illustrating the dei ail 'construction o't'niv improved machine; Fig. 2, is a plan oi" the machine with its parts in the positions Shown in Fig. .1; Fig. 3, is a plan'of the machine after its revoluble frame has been turned 180o: Figs. et and 5 are respectively a plan and a front elevation 'of the cap applying device `torming part nl' my invention, Fig. (i, is a detion ot' the main frame. of the machine, to

the opposite ends of which are rigidly connected upright?.l and f. Between the top portions ot' these uprights extends a frame G5 4 revoluble on a horizontal axis and having atits ends trunnions 4 fitted to bearings in the uprights 2 and S whereby such movement is rendered possible. This trame may be held in either one of wo positions 70 180 from each other by means of a. pin 5 mounted in the upright 3 'and capable of entering either of two holes G and G in the adjacent ends -of said frame; there being provided a lever 7 (preferably foot oper--75 ated) pivoted on the upright 3 for shifting the position otl this pin atwill.

i As shown in the two plan views, the frame t is of an open construction and includes two widely separated side members 4b be- 80 tween which is mounted a vertially movable slide 8 co-acting with suitable guideways' on an upward extension 9 projecting from what is, under operating conditions; the rear end of the frame l.' .ln this part 85 9 is mounted a screw l0 having an operating handle 1l and engaging the slide 8 in such manner as to raise or lower it when said handle is turntd.I Said slide 'is provided with horlzontal giudeways S2l 1n whichvis 90 mounted a horizontally movable slide '12 having a rack 13 formed in :its upper portion and designed to co-act with a pinion 14. This latter is, mounted on a shaft l5 carried in bearings )on the vertically inovahle slide S and also having fixed to it a wheel 1G which has en one face a series ot teeth, indicated at 1T. capable ot' engagement by a pawl 1S carried on a lever or handle 19 which may be swungl away from said wheel in order that it and hencethe pinion ll 4may be moved at will to shift the slide V1Q in a horizontal line.

rl`he under side of the horizontally movable slide 12 is provided with curved under 105 cut guide\.va vs tor the reception ot a carriage 13 which, by means of a shaft 19, supports a sleeve 20; there being mounted on said sha t`t a semnent of a worm gear. as indicated in dotted lines in Fig. l, designed to no mesh Witha worm 2l carried on a spindle having bearings-in the sleeve 20 and capable .of operation by means of a handle 22 to.

swing said sleeve upon its pivot. v

Within'the'fsleeve is rotatably' mounted a eyhndrlcal piece 23. having worm teeth 4 indicated at 24-.designed to be engaged by a Y Worin indicated in dotted lineslin Fig. l, to whichis fixed a handle 23b whereby the piece 23 maybe rotated within the sleeve. Said piece 23 has a forwardly projecting portion 23fin which' are formed curved guideways for the receptionvof projecting lugs belonging to'twofheel wiping jaws 75 pivotally connected to a pair of links 76 movably held to the end of a bar'77 guided within the piece '23 and capable of reciprocation by means of' a nand lever '78. This latter is pivoted to an arm 79 rigidly fixed to said piece 23.

inany adjusted --j'aosition-'by'fmeans of a nut 30; .the lowerend of-this' rodprojecting downwardly soas to be capable of engaging the last X'.- For supporting the rear part of such -1ast,"I provide an adjustable arm 31'co'nnected 'to the carriage 8, from which it extends downwardly and under the parts heretofore described; the construction and arrangement beingsuch as to permit this arm being locked or clamped'in any given position.

The front portion ofthe last is carried by an' arm 32, shown in Figs. 1 and 3, and

Aforming part of the frame 4. Said frame also supports ahorizontally 'reciprocable carriage 33.in which is mounted a series of pairs of jaws of the detail construction shown in Fig. 6 and designed to grasp the leather of an upperso as to stretc it over the toe and front portions of a last. In order to support and operate said jaws, the carriage 33 has a downwardly and rearwardly projecting arm 34 having a bearing serving as a guide for a vertically extending rod 35 which is provided with a lateral extension 36 at its lower end so as to be capable of removablyr engaging the suitably formed upper end 37 of a foot operated'bar 38 guided in the main frame l. l

The construction of the end 37 1s such that the part 36 is free r'zo disengage it when tlie frame' 4 'is swung on its trunnions` 4a and is also'freeto move longitudinally of the 'machine while still remaining operatively com ieeted` to said bar 38. The upper end of the rod 35 carries a plate 39 -which has a spring 40 confined between it and the arm 34; the arrangement being such that when the parts 36 and 37 are 1nengagement, 1t 1s f possible,vby drawing down on the bar 38,

to likewise :draw down the plate 39 against the action of said spring.

As shown in Fig. 2,.the rear end of the carriage 33 has a semi-elliptical recess 4l v guide boxes 42 is open and has mounted within it a stem 45 which carries a forwardly projecting jaw 44; said stem being hollow and of substantially rectangular sec ti'on so as to snugly tit within the space 42a of the guide box 42. The passage within th'e stem 45 ofeaeh jaw is preferably rectangular in section and has movably m0unt.

ed in it the rectangular stem section 46 of the second or upper jaw 47, which lpreferably is inclined forward so that one of its faces may co-act with the jaw 44 to grip a piece of leather. The lower end of the-stem V46 of each jaw 47 is pivoted to the suitablyformed headA 48 of 'a bolt-49 inovably vcarried by the plate 39; the arrangement being such that said bolts extend `below this yplate and have springs 50 confined between their lower ends and said plate. A nut-or other suitable form ofabutlnent 51 is .mounted on each of the bolts 49 above the plate 39 so as' to adjustably limit-the amount of its possible downward movement. In addition to the above, I preferably mount a spring 52 on each of the stems 46 between the upper end 48-of the bolt 49 and the lower end of the stem 45 of the j'aw'44; it being possible by this means for the latter jaws to be moved independently of the jaws 47 and likewise for both of said jaws to be moved together after they have gripped a piece of leather. i

In order tov reciprocate the carriage 33, I

provide a lever 53 pivoted to the frame 4 atl .54 and suitably connected to a Stud 55 projecting downwardly from the body of the carriage 33; it being seen from Fig. 3 that the handle of said lever projects from one side of the frame of the-machine so as to be readily grasped and operated.

The frame 4 extends upwardly from theV front lportion of the carriage 33 and is` provided with a cylindrical bearing 4d for a'- sleeve 56 having formed in its surface a series of worm teeth 57 designed to be engaged by a worm' 58 mounted in the bearing structure and capable of being turned .by a handle 59 to rotate said sleeve. This latter has a vrearwardly projecting portion 56 serving as a support and provided with guideways fortwo wiper jaws 60 so placed as to' be capable of beingbrought intoengagenient with and wiping or smoothing the leather' of an upper after this has been stretched over the last X, as hereafter described. For operating these jaws, I provide a bar 61 preferably of rectangular section and operative within the sleeve 56; conneet-ing this to the jaws4` by links 62 and actuating it by means of a hand lever 63 suit-y ably supported on said sleeve. also has projecting rearwardly from it a structureA 65 to which is pivoted an arm 66; it being possible-to swing this arm up or down as desired by means of a reciprocable rod 67 connected to it by a-link 68. This rod is capable of operation by means of a hand lever 69' shown in dotted lines in Fig. 2 and also illustrated in Fig. 4. lAs shown best in Figs. 1, 4, and 5, thisnarm has depending from its end three levers, of which one is indicated at 70 and the others are shown at` 71; each of these having near'its lower end a recess for the reception of the flange 72 on v a toe cap 73. All the levers `are Inormally maintained in engagement with this fiange by a spring 74, thoughthey are capable of being turned on their pivots against the action or said spring to release the cap. This latter"is"preferably made of steel or other springy light material and is designed to fit over the toe of a shoe so 'as to confine or hold the leather of the upper inposition thereon after it has been properly stretched, as hereafter described. vFor this lpurpose the cap has aroundits lower edge an 1nwardly projecting flange'73a of such dimensions as to be'capable of springingover and tightly fitting the toeof ,the last after the leather has been applied thereto, to maintain this latter in any given position. j

Vith the above described arrangement of parts, a last suitable for the work is mounted on the supporting arms 31 and 32, being held inplace on the former by engagement with a sharp point 31a thereon. The bolt or pin 29 is then placed in its hole in the last and the carriage 18 is swung in its guide to suitably position the last for the operation to be performed on it; the part 8 being raised or lowered as may be necessary, by suitable operation of the handle 11, to bring the last to the proper level. Likewisev the handle 19 ismanipulated to free the wheel 16 which may be operated toV move the last backward or forward until it is in the. proper position. Y v l lVith the various arts'of the machine in the positions shown inFig. 1, the previously .assembled upperis4 then applied to thelast' and is laid by hand between the jaws 44 and 47 of each pair, these being normally in their separated positions. By means of a suitable treadle or other device (not shown) Ithe bar 38 is then drawndownwardly, thus likewise This latter' drawing down'the rod 35 and all of the jaws 47. These are thus caused to co-act with the jaws 44 to grip the leather of the upper and thereafter the continued downward movement of the bar- 38 causes all of the pairs of jaws to be bodily drawn down so that said leather isproperly stretched over the front of the last. The handle 53 is now moved toward the rear of the machine, thus moving the carriage 33 and with it all of the jaws in the same direction thereby more tightly stretching the leather and drawing its front lower edge under the toe. The handle 63 is now oscillated, thereby causin the wiper jaws to engage the upper aroun the lower portions of the toe and sides of the last so as to wipe or press'the overlapping toe port-ions over the insole and force the same squarely into. the shoulder or channel of the insole, at the same time properly smoothing the `leather in the desired man-- ner. Said handle 63 is then drawn toward the front of the machine and a cap 73 placed in position on the levers and 71, though if desired these latter, with their associated parts, may be omittedand the cap placed by hand. By moving the lever 69 to the rear, the arm 66 is swung downwardly and said cap is placed over the toe ofthe last; its

ianges 73 extending under the bottom of said last and tightly confining the stretched leather thereto in its smoothed position. By pressing down on the .upper end'of the lever 70 against the action of the spring 74, this lever with the two levers 71 are turned on their pivots and made to disengage the capV 7 3, which is thus left in position on the last.

By operating the lever 7, the pin 5 is withdrawn from the hole 6a so that the frame 4 may be turned 180 on its trunnions, thereby disengaging the members of the coupling formed by the parts 36 and 37 and bringing uppermost the bottom of the last, with the various parts occupying the positions shownV .in Fig. By suitably manipulating the handles 22 and 231 the wiper jaws 75 may be adjusted so as to be capable of properly operating on the heel portion of the upper, when'by oscillating the lover 7S, said jaws are brought into engagement with and caused to wipe or smooth. the upper around the lower edges of the heel portion thereof. Thereafter those edges of the upper which project below the heel are drawn inwardly over the bottom of the last and either tacked or wired thereto or held in position by a portable clamp, after which the pin 5 is withdrawn from the hole 6 of the frame 4 and this latter is swung back into the position shown in Fig. l, whereupon the last maybe removed and another substituted' therefor.

From the above description it will be noted that my machine may be quickly adjusted to operate either on ri ht or left lasts, for which pur oseI provi e the structure 12 with its a justable carriage 13. Likewise the support for the rear end of the last may be raised or lowered to accommodate it for the reception of lasts of various styles.
